ROOF-JOINT.

pipe where it passes through the roof of abuilding.

It is the object of the present invention to provide a simple and inexpensive joint of this kind, and also one which can be easily and quickly applied, and which may be employed on roofs of. different slopes or pitches.A

Vith these objects in View, the invention consists in a novel construction and arrangement of parts to be hereinafter described and claimed, reference being had to the accompanying drawing forming a part of this specification, in which drawing- Figure l is a plan View of the device partly in section. Fig.l 2 is a vertical section on the line 2 2 of Fig. 1.

Referring specifically to the drawing, 5 denotes a frusto-conical, sheet-metal sleeve to the lower edge or base of which is secured an outstanding iange 6 whereby the sleeve is secured to the roof (not shown) in any suitable manner. The base of the sleeve is cut at a slant, and the iiange extends at a corresponding angle tothe sleeve-so that the device may be applied to a sloping roof. For a flat roof the parts will be constructed so that the sleeve extends perpendicular to the base flange. The diameter of the sleeve is such that the soilor other pipe 7 may pass therethrough.

a The sleeve 5 is divided longitudinally from the top to its base, so that its upper end may be contracted around the pipe 7 to form a tight joint therewith. At one of the edges formed by dividing the sleeve as stated, the material is bent' back or doubled as indicated at 8, and then a return bend 9 is made, which latter is spaced from the part 8 to form a slot to receive the other edge of the sleeve, said edge fitting snugly in the slot so that a tight joint is eifectcd. At the top of the sleeve, adjacent to the two ends thereof, are secured outstanding ears 10 having alined apertures through which passes a screw or 4bolt 11, by means of which latter the sleeve may be tightly drawn together around the' pipe for the purpose stated. It will be understood that it is only the top of the sleevel which is clamped around the pipe, the diameter of the remainder of the sleeve being such that the pipe is spaced therefrom, which enables the device to be readily adjusted to roofs of different pitches.

In assembling the parts, the sleeve is slipped down over the pipe and secured to the roof by means of the base flange The conical shape of the Sleeve permits this to be readily done. After the device has been properly positioned on the roof, the upper end of the sleeve is clamped around the pipe as already described, which completes the joint.

I claim:

A roof jointcomprising a frusto-conical Sleeve having a continuous outstanding securing flange at its base, and split longitudinally from the top to but not through said base to permit 'contraction ot' its upper portion, the base being left intact, and means at the top of the sleeve for tightening the samearound the pipe.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES AUGUSTUS OVERTON.
